  abstract = {Construction projects persistently fail to meet planned time, cost, and quality targets due to fragmented planning, late constraint discovery, and reactive decision-making. Despite growing interest in both Lean Construction and Building Information Modeling (BIM), a structured, planning-phase-focused conceptual framework that explicitly links Last Planner System (LPS) workflows to BIM functionalities remains absent from the literature. This paper addresses that gap through a structured literature synthesis of 50 peer-reviewed sources. The principal contribution is a Lean-BIM Planning Framework that maps each LPS planning level - master scheduling, phase planning, lookahead planning, and weekly work planning - to specific BIM tools and mechanisms, including 4D simulation, clash detection, automated quantity take-off, and common data environment. Synthesized findings indicate that Lean-BIM integration can increase plan reliability, reduce waste from rework and idle time, improve resource coordination, and enhance cross-disciplinary collaboration. The paper also consolidates key implementation barriers: BIM interoperability constraints, level-of-detail mismatches, investment and training demands, and organizational resistance to change. The framework is intended to guide future empirical research and early-stage practical implementation of integrated Lean-BIM planning approaches.},
